ADJUSTABLE CHIMNEY.

SPECIFICATION forming part of Leners Patent No. 377,899, dared February 14, laas'.

Application filed July 2, 1887. Serial No. 243,299. (No model.)

.To all whom it may concern.-

Be it known that we, ISAAC N. JONES and PETER C. ELsEE, citizens of the United States, residing at Dupont, in the county of Putnam and State of Ohio, have invented certain new and useful Improvements in an Adjustable Chimney, of which the following is a description.

Our invention relates to an improvement in adjustable chimneycaps; audit consists in the peculiar construction that will be fully set forth hereinafter, and its essential features pointed out in the'claims.

In the accompanying drawings, Figure 1 is an elevation of an adjustable chimney-cap embodying our improvements. Fig. 2 is a vertical longitudinal sectional view of the same. Figs. 3 and 4 are detailed top plan views of the cap and slide, respectively.

A represents a sloping roof of abuilding,on which is secured a plate, B, of metal, and of suitable length and width. The said plate may form part of a metalliecovered roof, or may be separate therefrom.v In the center of the plate is an opening, O,which registers with a similaropening in the roof, and through which the stove-pipe is passed. The said plate is provided on its upper side with vertical iianges D,which form the sides of the opening C.

E represents a semicircular cap, which is made of cast-iron or other suitable material,

and is provided in its curved upper side with an opening, F, of suitable length Vand width. The lower edges of this cap tit down over the flanges D of the-plate, and are secured thereto by means of suitable bolts or rivets, as shown.

The curved slide G is made of cast-iron or other suitable material, and is adapted to iit on the convex upper side of the cap, as shown.

The said slide is provided with depending side iianges, H, which bear against opposite sides of the cap and serve to secure the slide rmly thereon, and in the said side anges are longitudinal curved slots I, of proper length and width. Set-screws K extend through the said slots and engage the sides of the cap at the center of the saine, the functions of the screws being to secure the slide at any desired adjustment on the cap. In the upper side of the slide, 5o at the center thereof, is an opening, L, having avertical collar or ange, M, of suitable size and shape..

N-represents the draftpipe,which projects above the roof, is provided at its upper end with a cowl, O, and has its lower end secured to the iange or collar M.

The slide,whe'n placed in position on the cap, is first adj usted so as to arrange the draft-pipe N in a perfectly vertical position, and the set- 6o -screws are then tightened,so as to prevent vthe slide from slipping.

Au adjustable chimney-cap thus constructedV is adapted to arrange and maint-ain the draftpipe in a vertical position, no matter what the vangle of the roof ,on which the cap vis placed may be, is very cheap and simple, is easily se cured on the roof, and will be found of great utility on workshops, summerkitchens, and other structures. y

Having thus described our invention, we claim- 1. The combination, with the chimney-cap, of the slide secured thereon andcarrying the draft-pipe and capable of curvilinear adjust- 7 5 ment.

2. The combination of the cap having the convex upper side provided with the opening, and the slide adapted for the attachment ofthe pipe and tting on the convex upper side of 8o the cap and adjustable thereon, forthe purpose set forth, substantially as described.

3. The combination of the plate adapted to be secured on the root` and having the opening and the iianges D, the cap having the convex S5 upper side provided with the opening F, the lower edges of said cap fitting overthe flanges D, and the 'slide fitting on the convex upper side of the cap, adjustable thereon, having the opening L` registering with opening F, and 9o adapted for the attachment of the pipe, substantially as described.
